These Playboy Bunnies could be showing off more than their cottontails.

The stars of NBC’s upcoming series, “The Playboy Club,” have contractually committed to baring all — if necessary.

This stipulation is unheard-of for a network show — where nudity is verboten — but it’s believed that the clause, reported by Variety, is intended for the show’s release on DVD and in domestic and foreign cable syndication.

“Nudity as defined above and/or simulated sex acts may be required in connection with player’s services in the pilot and/or series,” reads the clause signed by stars Amber Heard, Eddie Cibrian, Jenna Dewan-Tatum and Leah Renee.

The actors, however, can’t be forced to shoot nude scenes. If it came to pass that nudity was included, the particular scene in the script must be given to the actor(s), allowing them the opportunity to consent or decline, according to the report.

Insiders tell Variety that no nudity was included in the pilot episode, and that there are no plans to include nudity if the pilot is picked up for a (likely) series run by NBC.

There are also no plans to shoot two different versions of the show a la HBO’s “The Sopranos” — which scrubbed the nudity and profanity — with an eye toward the show’s syndicated run.

“The Playboy Club” is based on the “Swinging ’60s”-era nightclubs spun off from Hugh Hefner’s Chicago-based Playboy magazine.

(The pilot is set in 1963 at the original Playboy Club in Chicago.)

The clubs featured scantily clad waitresses in bunny outfits (complete with cottontail).

Heard is headlining the series as Maureen, a new Playboy Club hire with “an untethered, unconscious sexuality,” according to Variety.

She recently posted a photo of herself, in her Playboy Bunny outfit, on her Facebook page.

Heard is best-known for her role in the short-lived CW series “Hidden Palms” and has also co-starred on the big screen in “Pineapple Express,” “Never Back Down” and “Zombieland” — opposite “The Social Network” star Jesse Eisenberg.
